Abstract

Isotactic index improvement is achieved for C₃ and higher alpha olefins in systems containing a catalyst com­ ponent comprising titanium supported on a magnesium hal­ ide support. The titanium component is formed by copulverizing the magnesium halide with one or more elec­ tron donors followed by treatment with liquid titanium halide. The improvement is achieved by using a dialkylaluminum alkyl phenoxide component with the trialkylaluminum co­ catalyst normally used. In slurry polymerizations, the isot­ actic index of the polymer has been improved. It is possible to achieve a variable melt flow index for polypropylene while maintaining good isotactic index. Isotactic index is retained at high levels even though the temperature and/or time of polymerization is varied.
